Coverity warns of some descriptor leaks in this function (and in
rearrange_squash). I think you get those emails, so I won't repeat the
details here. But I while looking at them I did notice something it
didn't mention:

This should probably check the result of open(). I know write_in_full()
will fail if fd is -1, but we'd rather show the user the errno from
open(), not EBADF.
Technically the free() calls from todo_list_release() can also munge
errno before you print it. You might want to just call error_errno()
first, then do the cleanup (including the missing close()).

Ditto here.
